PROBLEM TO BE SOLVED: To provide a three-dimensional molding apparatus configured in such a manner that upon replenishing a new filament resin, each filament resin can be introduced into a heater nozzle without removing a filament resin remaining in the head.SOLUTION: The three-dimensional molding apparatus produces a three-dimensional molded object by discharging a fused filament resin, and the apparatus includes: discharge means that fuses an introduced filament resin to discharge; conveying means that includes a rotation member formed into substantially cylindrical in which a first region with a larger diameter and a second region with a small diameter are alternately formed and that conveys the filament resin by rotating the rotating member; and first guiding means that has a concavo-convex structure formed in a predetermined region and is arranged to fit the above first region and the above second region of the conveying means to the concavo-convex structure region thereof in a non-contact manner so as to linearly guide the filament resin conveyed by the conveying means to the discharge means.SELECTED DRAWING: Figure 3 |
